My first fixed gear was a Kilo TT I owned for a brief period of time. I tried it out and just didn't think I liked riding fixed. IIRC it was geared something like 75"-80". Ended up selling it after not too long (really regretting that, thinking about it now

)
It wasn't until a few years later that I found some old track hubs, built some wheels around them, and converted a road frame in to a porteur bar cruiser. This time I decided to go for a much chiller ~70" 44x17 because this bike was just going to be for riding rail trails and I ended up liking that gearing a lot.
